Sugar Profile, Mineral Content, and Rheological and Thermal Properties of an Isomerized Sweet Potato Starch Syrup
Currently, corn is used to produce more than 85% of the world's high fructose syrup (HFS). There is a search for alternative HFS substrates because of increased food demand and shrinking economies, especially in the developing world. The sweet potato is a feasible, alternative raw material. This study isomerized a high glucose sweet potato starch syrup (SPSS) and determined its sugar profile, m...
متن کاملThe Pasting and Gel Textural Properties of Corn Starch in Glucose, Fructose and Maltose Syrup
The pasting and gel textural properties of corn starch in syrup at different concentrations were investigated by Rapid Visco Analyzer (RVA) and Texture profile analysis (TPA) tests. The results showed that the pasting temperatures of corn starch greatly increased, especially at higher sugar concentration. Increasing concentration of syrup caused an increase in peak, trough and final viscosity o...
متن کاملEffect of Maltodextrins on the Rheological Properties of Potato Starch Pastes and Gels
The study examines the effects of maltodextrins saccharified to various degrees on some rheological properties of potato starch dispersions. Pasting characteristics, flow curves, and mechanical spectra were determined for native potato starch and for its blends with potato maltodextrins having dextrose equivalents (DE) of 10.5, 18.4, and 26.5. The results showed that medium-saccharified maltode...
متن کاملThe Effects of Different Methods of Date Syrup Purification on the Physicochemical Properties of Produced Date Syrup Powder
Date syrup powder is a new product which can be used as sugar substitute. First, the date syrupwas spread out on a foil and placed in the oven at 60°C for 24 hours. Date syrup was separated from the foil andgrinded. 2% agar and 2% starch were added and syrup with agar and starch that was in a lumpy shape werecrushed and spread on the foil and placed at 60°C for 24 hours. Powdered granules, agar...
متن کاملCorrelation of Microscopic Structure of Corn Starch Granules with Rheological Properties of Cooked Pastes
The progressive geometric changes that occur in swelling of corn starch granules during heating throughout the range of gelatinization (63-72°C) and at higher temperatures when substantial amount s o f soluble starch are released from the granule were observed by scanning electron micro s copy (SEM). Corn starch granules beg in to swell radially, then undergo radial contraction and random tange...
